Explanation
Also known as nylon resin, it is the general name of macromolecule compounds containing multiple repeated amide groups (- NH-CO -) in the main chain structure. Polyamide can be divided into two kinds of natural polymer: natural source and artificial synthesis. Protein in natural polymer can be regarded as the condensation polymer of amino acid, which is called poly amino acid in the biological world. This kind of macromolecule plays an important role in the life process and forms the basis of cells and the whole matrix.
